A fixed road surface detection device and method using structured light

Abstract

The invention relates to the field of active three-dimensional detection and image recognition, in particular to a fixed road surface detection device and method using structured light. Aiming at the problems existing in the prior art, the present invention provides a fixed road surface detection device and method using structured light. The invention uses the detection unit to project the known structured light in a directional manner, assists the two-dimensional camera to take pictures of the area to be detected on the road surface, and then uses the control processing unit to detect the abnormality of the captured image according to the target detection method to determine whether there is an intruder or Judging whether the flatness of the pavement meets the requirements, and alarming the abnormal conditions found. Repeat the above method for all areas to be detected on the runway to achieve a complete runway pavement detection.

Description

technical field [0001] The invention relates to the field of active three-dimensional detection and image recognition, in particular to a fixed road surface detection device and method using structured light. Background technique [0002] The surface condition of the airport runway has a direct impact on the safety of flight takeoff and landing. The runway must be kept flat and clean, but runway damage and intrusion of foreign objects pose a serious threat to the safety of taking off and landing flights. Runway damage refers to problems such as runway weathering, cracking, breaking, and falling stones caused by various reasons such as aging and external forces. Invasive foreign objects refer to certain foreign substances, debris or objects that may damage the aircraft, such as metal parts, waterproof plastic sheets, broken stones, newspapers, bottles, luggage tags, etc. [0003] In order to ensure the safety of flight take-off and landing, the condition of the runway pavem...

Problems solved by technology

However, in the actual operation of large airports, it is difficult to frequently close the runway for inspection

The lack of inspection of the runway for a long time increases the risk of accidents caused by foreign objects intruding on the runway
